Fairchild entered Friday's game after Jake Fraley (ankle) was removed and went 1-for-3 with a two-run home run in an 8-3 loss to Milwaukee.
Fairchild swatted his eighth homer of the season as part of the Reds' three-run seventh inning. It came off a right-hander; Fairchild is batting .152 with a .522 OPS against righties this season. It's unclear why Cincinnati manager David Bell went with Fairchild instead of the lefty-hitting Will Benson, who has slightly better results against right-handers. Bell told MLB.com following the game that Fraley is "fine" and could return to action Saturday.
